BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention relates to hand grip sleeves and more particularly to a hand grip sleeve for wrapping about the grip of a golf putter to increase the diameter of the grip area of the golf putter for gripping tightly and comfortably. (b) Description of the Prior Art

Golf is a game that requires intense concentration and a positive mental attitude on the part of the player. In order to achieve excellent results, golf players not only require skill and techniques, but also need to fully understand and use their clubs. In a golf game, wood clubs, iron clubs and putters will be used. The putter is used about 40% of the time in each round of the game. Putting technique requires high stability of the player's body and hands. However, due to lack of stability, a golf player may twist the wrist during putting, leading to inaccurate hitting and poor score. Therefore, club manufacturers are all trying hard to make putters in accordance with the rules of golf that are easier for players to achieve hitting stability.

According to existing studies, most people believe that the diameter of the plastic grip at the end of the putter has a great concern with wrist stability. The smaller the grip diameter is, the easier the turn of the wrist during putting will be. On the contrary, increasing the diameter of the grip can enhance wrist stability during putting. This condition is more obvious in amateur players. Therefore, many golf accessories manufacturers provide large size hand grips for golf players to replace thin hand grips of their putters, for the purpose of preventing wrist vibration during putting and enhancing putting accuracy.

However, a large size hand grip simply uses a relatively lighter material and provides a large diameter. The mounting structure remains unchanged. During installation, the original hand grip is detached from the putter, and then the large size hand grip is slipped onto the rear end of the handle of the putter, and then a screw is driven into the rear end of the large size hand grip and the rear end of the handle of the putter to affix the large size hand grip to the handle of the putter. This installation procedure is complicated.

Therefore, it is desirable to provide a hand grip sleeve for golf putter that can easily and detachably be wrapped about the hand grip of a golf putter by a user to increase the diameter of the hand grip without removing the hand grip from the golf putter.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances in view. It is therefore the main object of the present invention to provide a hand grip sleeve for golf putter, which provides a longitudinal opening and a fastener for closing and opening the longitudinal opening so that a user can easily and detachably wrap the hand grip sleeve about the grip of a golf putter to increase the diameter of the grip area of the golf putter for gripping tightly and comfortably.

To achieve this and other objects of the present invention, a hand grip sleeve is adapted for wrapping about a grip of a golf putter, comprising a flexible sleeve defining a sleeve hole extending from the front end to the rear end and a longitudinal opening cut through the peripheral wall, and a fastener provided at the flexible sleeve at two opposite sides of the longitudinal opening and operable to open or close the longitudinal opening.

Further, in one embodiment of the present invention, the fastener comprises a strip of hook material and a strip of loop material respectively affixed to the flexible sleeve at two opposite sides of the longitudinal opening. In another embodiment of the present invention, the fastener comprises a zipper affixed to the flexible sleeve at the two opposite sides of the longitudinal opening and operable to open and close the longitudinal opening. In still another embodiment of the present invention, the fastener comprises a plurality of male snap members and female snap members respectively affixed to the flexible sleeve and arranged at the two opposite sides of the longitudinal opening.

Further, the flexible sleeve is made of a foam plastic, having a surface layer bonded to an outer perimeter of the flexible sleeve. Further, the surface layer can be made of plastic sheet, leather or synthetic leather.

Further, an end cap is capped on the rear end of the flexible sleeve.

Further, an anti-slip structure is provided at the inner surface of the peripheral wall of the flexible sleeve inside the sleeve hole. In one example, the anti-slip structure comprises a plurality of raised dots/strips formed on the inner surface of the peripheral wall of the flexible sleeve. In another example, the anti-slip structure comprises an anti-slip skin adhered to the inner surface of the peripheral wall of the flexible sleeve.

Thus, by means of the longitudinal opening of the flexible sleeve, the hand grip sleeve can be directly and easily attached to the grip of the golf putter. Thereafter, the fastener is fastened up to close the longitudinal opening. This installation procedure is easy and simple. Thus, the hand grip sleeve greatly increases the diameter of the grip area of the golf putter, and a player can tightly grip the hand grip sleeve to swing the golf putter steadily with the two hands. In conclusion, the hand grip sleeve has the characteristics of ease of mounting and dismounting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 and 2, a hand grip sleeve for a golf putter in accordance with the present invention is shown surrounding a grip 201 of a golf putter 20 to increase its diameter for enabling a player to grip the golf putter tightly. The hand grip sleeve 10 comprises a flexible sleeve 1 made of a foam plastic having a proper weight for gripping comfortably. The flexible sleeve 1 defines therein a sleeve hole 11 extending from a front end 12 of the flexible sleeve 1 to a rear end 13 of the flexible sleeve 1. The sleeve hole 11 can be a through hole, or a blind hole closed at its rear end. The flexible sleeve 1 further defines a longitudinal opening 14 cut through the peripheral wall thereof and extending from the front end 12 toward the rear end 13. A fastener 15 is provided at two sides of the longitudinal opening 14 for closing or opening the longitudinal opening 14, as shown in FIG. 3 and FIG. 4. By means of the fastener 15, the flexible sleeve 1 can be conveniently wrapped about the grip 201 of the golf putter 20.

Referring to FIGS. 2-4, the fastener 15 comprises a strip of hook material 151 fixedly provided at one side of the longitudinal opening 14, and a strip of loop material 152 fixedly provided at the other side of the longitudinal opening 14. The strip of hook material 151 and the strip of loop material 152 can be fastened together or separated by the user to close or open the longitudinal opening 14, facilitating wrapping the flexible sleeve 1 about the grip 201 of the golf putter 20. In an alternate form as shown in FIG. 5 and FIG. 6, the fastener 15 is a zipper 153 secured to the flexible sleeve 1 at the two opposite sides of the longitudinal opening 14 and operable to close/open the longitudinal opening 14. In another alternate form as shown in FIG. 7, the fastener 15 comprises a plurality of male snap members (studs) 154 arranged in a line along one side of the longitudinal opening 14, and a plurality of female snap members (sockets) 155 arranged in a line along the opposite side of the longitudinal opening 14. By means of fastening up the male snap members (studs) 154 and the female snap members (sockets) 155 or unfastening them, the longitudinal opening 14 can be closed or opened.

Referring to FIG. 2, FIG. 5 and FIG. 6, a surface layer 2 is bonded to the outer perimeter wall of the flexible sleeve 1. The surface layer 2 can be prepared from plastic sheet, leather, synthetic leather, or any other suitable material. Through the design of the surface layer 2, the invention gives an enhanced grip feel and improves the quality of the grip. Further, text, graphics and/or patterns can be printed on the surface layer 2.

Referring to FIG. 8 and FIG. 9, in the case when the sleeve hole 11 is a through hole extending from the front end 12 of the flexible sleeve 1 to the rear end 13, a rear end cap 16 is capped on the rear end 13 of the flexible sleeve 1 to enhance the positioning stability and quality of the hand grip sleeve 10 and to prohibits the hand grip sleeve 10 from a forward movement relative to the grip 201 of the golf putter 20.

Referring to FIG. 9, an anti-slip structure 17 can be provided at the inner perimeter wall of the flexible sleeve 1 inside the sleeve hole 11. In one example, the anti-slip structure 17 comprises a plurality of raised dots 171 (or raised strips) on the inner perimeter wall of the flexible sleeve 1 inside the sleeve hole 11. In another example, the anti-slip structure 17 comprises an anti-slip skin 172 adhered to the inner perimeter wall of the flexible sleeve 1 inside the sleeve hole 11. When wrapping the flexible sleeve 1 about the grip 201 of the golf putter 20, the anti-slip structure 17 enhances the friction between the periphery of the sleeve hole 11 and the surface of the grip 201, thereby enhancing the wrapping quality and non-slip stability.

Further, it is understood that, according to golf game rules, the grip of a golf putter is not limited to a circular shape. Thus, the cross-sectional shape of the flexible sleeve 1 can be changed subject to substantial requirements. For example, the flexible sleeve 1 can be made a circular sleeve as shown in FIG. 2, or a circular sleeve with at least one plane 18 at the outer perimeter as shown in FIG. 10 and FIG. 11, or a rectangular sleeve as shown in FIG. 12.

When using the hand grip sleeve 10, as shown in FIGS. 2-4, the flexible sleeve 1 of the hand grip sleeve 10 can be directly attached to the grip 201 of the golf putter 20 by means of the longitudinal opening 14. After the flexible sleeve 1 of the hand grip sleeve 10 is attached to the grip 201 of the golf putter 20, the fastener 15 is then fastened up to close the longitudinal opening 14. This installation procedure is easy and simple. Thus, as shown in FIG. 13, the hand grip sleeve 10 greatly increases the diameter of the grip area of the golf putter 20, and a player can tightly grip the hand grip sleeve 10 to swing the golf putter 20 steadily with the two hands.
